| In the Linux kernel, the following vulnerability has been resolved:
drm/msm/dp: fix bridge lifetime
Device-managed resources allocated post component bind must be tied to
the lifetime of the aggregate DRM device or they will not necessarily be
released when binding of the aggregate device is deferred.
This can lead resource leaks or failure to bind the aggregate device
when binding is later retried and a second attempt to allocate the
resources is made.
For the DP bridges, previously allocated bridges will leak on probe
deferral.
Fix this by amending the DP parser interface and tying the lifetime of
the bridge device to the DRM device rather than DP platform device.
Patchwork: https://patchwork.freedesktop.org/patch/502667/ |
| Inappropriate implementation in Passwords in Google Chrome prior to 143.0.7499.41 allowed a local attacker to bypass authentication via physical access to the device. (Chromium security severity: Low) |
| OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. Prior to version 2.4.15, a client that connects to cupsd but sends slow messages, e.g. only one byte per second, delays cupsd as a whole, such that it becomes unusable by other clients. This issue has been patched in version 2.4.15. |
| LogStare Collector contains an incorrect authorization vulnerability in UserRegistration. If exploited, a non-administrative user may create a new user account by sending a crafted HTTP request. |

slimbus: qcom-ngd: cleanup in probe error path

acquired/allocated to fix warnings visible during probe deferral:

| In the Linux kernel, the following vulnerability has been resolved:
md: Replace snprintf with scnprintf
Current code produces a warning as shown below when total characters
in the constituent block device names plus the slashes exceeds 200.
snprintf() returns the number of characters generated from the given
input, which could cause the expression “200 – len” to wrap around
to a large positive number. Fix this by using scnprintf() instead,
which returns the actual number of characters written into the buffer.

| In the Linux kernel, the following vulnerability has been resolved:
iommu/omap: Fix buffer overflow in debugfs
There are two issues here:
1) The "len" variable needs to be checked before the very first write.
Otherwise if omap2_iommu_dump_ctx() with "bytes" less than 32 it is a
buffer overflow.
2) The snprintf() function returns the number of bytes that *would* have
been copied if there were enough space. But we want to know the
number of bytes which were *actually* copied so use scnprintf()
instead. |

ASoC: qcom: Add checks for devm_kcalloc
As the devm_kcalloc may return NULL, the return value needs to be checked
to avoid NULL poineter dereference. |

incremented, we should use of_node_put() on it when not need anymore.

| In the Linux kernel, the following vulnerability has been resolved:
ip6mr: fix UAF issue in ip6mr_sk_done() when addrconf_init_net() failed
If the initialization fails in calling addrconf_init_net(), devconf_all is
the pointer that has been released. Then ip6mr_sk_done() is called to
release the net, accessing devconf->mc_forwarding directly causes invalid
pointer access.
The process is as follows:
setup_net()
ops_init()
addrconf_init_net()
all = kmemdup(...) ---> alloc "all"
...
net->ipv6.devconf_all = all;
__addrconf_sysctl_register() ---> failed
...
kfree(all); ---> ipv6.devconf_all invalid
...
ops_exit_list()
...
ip6mr_sk_done()
devconf = net->ipv6.devconf_all;
//devconf is invalid pointer
if (!devconf || !atomic_read(&devconf->mc_forwarding))

| In the Linux kernel, the following vulnerability has been resolved:
erofs: fix order >= MAX_ORDER warning due to crafted negative i_size
As syzbot reported [1], the root cause is that i_size field is a
signed type, and negative i_size is also less than EROFS_BLKSIZ.
As a consequence, it's handled as fast symlink unexpectedly.
Let's fall back to the generic path to deal with such unusual i_size.

perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()
pci_get_device() will increase the reference count for the returned
'dev'. We need to call pci_dev_put() to decrease the reference count.
Since 'dev' is only used in pci_read_config_dword(), let's add
pci_dev_put() right after it. |

| In the Linux kernel, the following vulnerability has been resolved:
bpf, x86: fix freeing of not-finalized bpf_prog_pack
syzbot reported a few issues with bpf_prog_pack [1], [2]. This only happens
with multiple subprogs. In jit_subprogs(), we first call bpf_int_jit_compile()
on each sub program. And then, we call it on each sub program again. jit_data
is not freed in the first call of bpf_int_jit_compile(). Similarly we don't
call bpf_jit_binary_pack_finalize() in the first call of bpf_int_jit_compile().
If bpf_int_jit_compile() failed for one sub program, we will call
bpf_jit_binary_pack_finalize() for this sub program. However, we don't have a
chance to call it for other sub programs. Then we will hit "goto out_free" in
jit_subprogs(), and call bpf_jit_free on some subprograms that haven't got
bpf_jit_binary_pack_finalize() yet.
At this point, bpf_jit_binary_pack_free() is called and the whole 2MB page is
freed erroneously.
Fix this with a custom bpf_jit_free() for x86_64, which calls
bpf_jit_binary_pack_finalize() if necessary. Also, with custom
bpf_jit_free(), bpf_prog_aux->use_bpf_prog_pack is not needed any more,
remove it.
