CVE-2025-71299 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: spi: cadence-quadspi: Parse DT for flashes with the rest of the DT parsing The recent refactoring of where runtime PM is enabled done in commit f1eb4e792bb1 ("spi: spi-cadence-quadspi: Enable pm runtime earlier to avoid imbalance") made the fact that when we do a pm_runtime_disable() in the error paths of probe() we can trigger a runtime disable which in turn results in duplicate clock disables. This is particularly likely to happen when there is missing or broken DT description for the flashes attached to the controller. Early on in the probe function we do a pm_runtime_get_noresume() since the probe function leaves the device in a powered up state but in the error path we can't assume that PM is enabled so we also manually disable everything, including clocks. This means that when runtime PM is active both it and the probe function release the same reference to the main clock for the IP, triggering warnings from the clock subsystem: [ 8.693719] clk:75:7 already disabled [ 8.693791] WARNING: CPU: 1 PID: 185 at /usr/src/kernel/drivers/clk/clk.c:1188 clk_core_disable+0xa0/0xb ... [ 8.694261] clk_core_disable+0xa0/0xb4 (P) [ 8.694272] clk_disable+0x38/0x60 [ 8.694283] cqspi_probe+0x7c8/0xc5c [spi_cadence_quadspi] [ 8.694309] platform_probe+0x5c/0xa4 Dealing with this issue properly is complicated by the fact that we don't know if runtime PM is active so can't tell if it will disable the clocks or not. We can, however, sidestep the issue for the flash descriptions by moving their parsing to when we parse the controller properties which also save us doing a bunch of setup which can never be used so let's do that.

CVE-2026-43479 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: net: usb: lan78xx: fix WARN in __netif_napi_del_locked on disconnect Remove redundant netif_napi_del() call from disconnect path. A WARN may be triggered in __netif_napi_del_locked() during USB device disconnect: WARNING: CPU: 0 PID: 11 at net/core/dev.c:7417 __netif_napi_del_locked+0x2b4/0x350 This happens because netif_napi_del() is called in the disconnect path while NAPI is still enabled. However, it is not necessary to call netif_napi_del() explicitly, since unregister_netdev() will handle NAPI teardown automatically and safely. Removing the redundant call avoids triggering the warning.

CVE-2026-43480 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: amd: acp3x-rt5682-max9836: Add missing error check for clock acquisition The acp3x_5682_init() function did not check the return value of clk_get(), which could lead to dereferencing error pointers in rt5682_clk_enable(). Fix this by: 1. Changing clk_get() to the device-managed devm_clk_get(). 2. Adding proper IS_ERR() checks for both clock acquisitions.
CVE-2026-43482 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: sched_ext: Disable preemption between scx_claim_exit() and kicking helper work scx_claim_exit() atomically sets exit_kind, which prevents scx_error() from triggering further error handling. After claiming exit, the caller must kick the helper kthread work which initiates bypass mode and teardown. If the calling task gets preempted between claiming exit and kicking the helper work, and the BPF scheduler fails to schedule it back (since error handling is now disabled), the helper work is never queued, bypass mode never activates, tasks stop being dispatched, and the system wedges. Disable preemption across scx_claim_exit() and the subsequent work kicking in all callers - scx_disable() and scx_vexit(). Add lockdep_assert_preemption_disabled() to scx_claim_exit() to enforce the requirement.
CVE-2026-43486 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: arm64: contpte: fix set_access_flags() no-op check for SMMU/ATS faults contpte_ptep_set_access_flags() compared the gathered ptep_get() value against the requested entry to detect no-ops. ptep_get() ORs AF/dirty from all sub-PTEs in the CONT block, so a dirty sibling can make the target appear already-dirty. When the gathered value matches entry, the function returns 0 even though the target sub-PTE still has PTE_RDONLY set in hardware. For a CPU with FEAT_HAFDBS this gathered view is fine, since hardware may set AF/dirty on any sub-PTE and CPU TLB behavior is effectively gathered across the CONT range. But page-table walkers that evaluate each descriptor individually (e.g. a CPU without DBM support, or an SMMU without HTTU, or with HA/HD disabled in CD.TCR) can keep faulting on the unchanged target sub-PTE, causing an infinite fault loop. Gathering can therefore cause false no-ops when only a sibling has been updated: - write faults: target still has PTE_RDONLY (needs PTE_RDONLY cleared) - read faults: target still lacks PTE_AF Fix by checking each sub-PTE against the requested AF/dirty/write state (the same bits consumed by __ptep_set_access_flags()), using raw per-PTE values rather than the gathered ptep_get() view, before returning no-op. Keep using the raw target PTE for the write-bit unfold decision. Per Arm ARM (DDI 0487) D8.7.1 ("The Contiguous bit"), any sub-PTE in a CONT range may become the effective cached translation and software must maintain consistent attributes across the range.
CVE-2026-43489 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: liveupdate: luo_file: remember retrieve() status LUO keeps track of successful retrieve attempts on a LUO file. It does so to avoid multiple retrievals of the same file. Multiple retrievals cause problems because once the file is retrieved, the serialized data structures are likely freed and the file is likely in a very different state from what the code expects. The retrieve boolean in struct luo_file keeps track of this, and is passed to the finish callback so it knows what work was already done and what it has left to do. All this works well when retrieve succeeds. When it fails, luo_retrieve_file() returns the error immediately, without ever storing anywhere that a retrieve was attempted or what its error code was. This results in an errored LIVEUPDATE_SESSION_RETRIEVE_FD ioctl to userspace, but nothing prevents it from trying this again. The retry is problematic for much of the same reasons listed above. The file is likely in a very different state than what the retrieve logic normally expects, and it might even have freed some serialization data structures. Attempting to access them or free them again is going to break things. For example, if memfd managed to restore 8 of its 10 folios, but fails on the 9th, a subsequent retrieve attempt will try to call kho_restore_folio() on the first folio again, and that will fail with a warning since it is an invalid operation. Apart from the retry, finish() also breaks. Since on failure the retrieved bool in luo_file is never touched, the finish() call on session close will tell the file handler that retrieve was never attempted, and it will try to access or free the data structures that might not exist, much in the same way as the retry attempt. There is no sane way of attempting the retrieve again. Remember the error retrieve returned and directly return it on a retry. Also pass this status code to finish() so it can make the right decision on the work it needs to do. This is done by changing the bool to an integer. A value of 0 means retrieve was never attempted, a positive value means it succeeded, and a negative value means it failed and the error code is the value.
CVE-2026-43160 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: mfd: macsmc: Initialize mutex Initialize struct apple_smc's mutex in apple_smc_probe(). Using the mutex uninitialized surprisingly resulted only in occasional NULL pointer dereferences in apple_smc_read() calls from the probe() functions of sub devices.
CVE-2026-43151 1 Linux 1 Linux Kernel 2026-05-14 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: Revert "media: iris: Add sanity check for stop streaming" This reverts commit ad699fa78b59241c9d71a8cafb51525f3dab04d4. Revert the check that skipped stop_streaming when the instance was in IRIS_INST_ERROR, as it caused multiple regressions: 1. Buffers were not returned to vb2 when the instance was already in error state, triggering warnings in the vb2 core because buffer completion was skipped. 2. If a session failed early (e.g. unsupported configuration), the instance transitioned to IRIS_INST_ERROR. When userspace attempted to stop streaming for cleanup, stop_streaming was skipped due to the added check, preventing proper teardown and leaving the firmware in an inconsistent state.

CVE-2026-43165 1 Linux 1 Linux Kernel 2026-05-13 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: hwmon: (nct7363) Fix a resource leak in nct7363_present_pwm_fanin When calling of_parse_phandle_with_args(), the caller is responsible to call of_node_put() to release the reference of device node. In nct7363_present_pwm_fanin, it does not release the reference, causing a resource leak.
CVE-2026-43159 1 Linux 1 Linux Kernel 2026-05-13 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix null dereference in find_network The variable pwlan has the possibility of being NULL when passed into rtw_free_network_nolock() which would later dereference the variable.
CVE-2026-43162 1 Linux 1 Linux Kernel 2026-05-13 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: media: tegra-video: Fix memory leak in __tegra_channel_try_format() The state object allocated by __v4l2_subdev_state_alloc() must be freed with __v4l2_subdev_state_free() when it is no longer needed. In __tegra_channel_try_format(), two error paths return directly after v4l2_subdev_call() fails, without freeing the allocated 'sd_state' object. This violates the requirement and causes a memory leak. Fix this by introducing a cleanup label and using goto statements in the error paths to ensure that __v4l2_subdev_state_free() is always called before the function returns.

CVE-2026-43166 1 Linux 1 Linux Kernel 2026-05-13 7.1 High
In the Linux kernel, the following vulnerability has been resolved: erofs: fix interlaced plain identification for encoded extents Only plain data whose start position and on-disk physical length are both aligned to the block size should be classified as interlaced plain extents. Otherwise, it must be treated as shifted plain extents. This issue was found by syzbot using a crafted compressed image containing plain extents with unaligned physical lengths, which can cause OOB read in z_erofs_transform_plain().
CVE-2026-43144 1 Linux 1 Linux Kernel 2026-05-13 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: Fix potential kernel oops when probe fails When probe of the sdio brcmfmac device fails for some reasons (i.e. missing firmware), the sdiodev->bus is set to error instead of NULL, thus the cleanup later in brcmf_sdio_remove() tries to free resources via invalid bus pointer. This happens because sdiodev->bus is set 2 times: first in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix this by chaning the brcmf_sdio_probe() function to return the error code and set sdio->bus only there.
CVE-2026-43145 1 Linux 1 Linux Kernel 2026-05-13 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: remoteproc: imx_rproc: Fix invalid loaded resource table detection imx_rproc_elf_find_loaded_rsc_table() may incorrectly report a loaded resource table even when the current firmware does not provide one. When the device tree contains a "rsc-table" entry, priv->rsc_table is non-NULL and denotes where a resource table would be located if one is present in memory. However, when the current firmware has no resource table, rproc->table_ptr is NULL. The function still returns priv->rsc_table, and the remoteproc core interprets this as a valid loaded resource table. Fix this by returning NULL from imx_rproc_elf_find_loaded_rsc_table() when there is no resource table for the current firmware (i.e. when rproc->table_ptr is NULL). This aligns the function's semantics with the remoteproc core: a loaded resource table is only reported when a valid table_ptr exists. With this change, starting firmware without a resource table no longer triggers a crash.
