| In the Linux kernel, the following vulnerability has been resolved:
net/rds: reset op_nents when zerocopy page pin fails
When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(),
the pinned pages are released with put_page(), and
rm->data.op_mmp_znotifier is cleared. But we fail to properly
clear rm->data.op_nents.
Later when rds_message_purge() is called from rds_sendmsg() the
cleanup loop iterates over the incorrectly non zero number of
op_nents and frees them again.
Fix this by properly resetting op_nents when it should be in
rds_message_zcopy_from_user(). |
| A vulnerability was detected in Artifex MuPDF up to 1.28.5. This impacts the function free_char_list of the file source/pdf/pdf-xref.c of the component Signature Locking. Performing a manipulation results in double free. The attack may be initiated remotely. The exploit is now public and may be used. The patch is named 3984925b660afb8a781ddf504021e91be1bc671e. To fix this issue, it is recommended to deploy a patch. |
| Double free in Remote Desktop Gateway Service allows an unauthorized attacker to execute code over a network. |
| L-SMASH through 2.14.5 contains a double free vulnerability in hevc_setup_first_summary() and h264_setup_first_summary() in importer/nalu_imp.c that frees borrowed codec-specific objects on error paths. Attackers can supply a crafted Annex-B elementary stream lacking a parseable SPS to lsmash_read_file() or the boxdumper, remuxer, or muxer tools, causing use-after-free, heap corruption, and crashes. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: release orphanage dir inode if chown fails
LOLLM points out that we leak the igrab'd reference to the orphanage
directory inode if chowning it fails. Fix that. |
| Double free in OpenSSH for Windows allows an authorized attacker to elevate privileges locally. |
| Double free in Microsoft Office Excel allows an unauthorized attacker to execute code over a network. |
| Double free in Windows Wired AutoConfig Service allows an authorized attacker to elevate privileges locally. |
| ImageMagick 7.1.2-30 before 7.1.2-32 contains a use after free vulnerability in the WBINFO decoder that occurs when a memory allocation fails during image decoding. Attackers can supply a crafted image that, when decoded under memory allocation failure conditions, causes freed memory to be reused, crashing the application. |
| Double free in Windows TCP/IP allows an authorized attacker to elevate privileges locally. |
| Double free in Windows Libarchive allows an unauthorized attacker to execute code over a network. |
| Double free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Double free in Windows Shell allows an unauthorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix query directory replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_query_directory_init() fails before the next send,
cleanup retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix query_info() replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_query_info_init() fails before the next send,
cleanup retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_ioctl() replay
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_ioctl_init() fails before the next send, cleanup
retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix change notify replay double-free
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_notify_init() fails before the next send, cleanup
retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_flush() replay
SMB2_flush() keeps its response buffer bookkeeping across replay
attempts. If a replayable flush response is received and the retry then
fails before cifs_send_recv() stores a replacement response, flush_exit
will free the stale response pointer a second time.
Reinitialize resp_buftype and rsp_iov at the top of the replay loop so
cleanup only acts on response state produced by the current attempt.
This fixes a double-free without changing replay handling for successful
requests. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix double-free in SMB2_open() replay
A response-bearing attempt can return a replayable error and free its
response buffer. If SMB2_open_init() fails before the next send, cleanup
retains the previous buffer type and frees that response again.
Reset response bookkeeping before each attempt to prevent the stale free. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: avoid double free of pool->stack on AQ init failure
otx2_pool_aq_init() frees pool->stack when mailbox sync or retry
allocation fails, but leaves the pointer unchanged. Later,
otx2_sq_aura_pool_init() unwinds the partial setup through
otx2_aura_pool_free(), which frees pool->stack again. The CN20K-specific
cn20k_pool_aq_init() implementation has the same bug in
its corresponding error path.
Set pool->stack to NULL immediately after the local free so the shared
cleanup path does not free the same stack again while cleaning up
partially initialized pool state.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still present in
v7.1-rc3.
Runtime validation was not performed because reproducing this path
requires OcteonTX2/CN20K hardware. |
