21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param In the `wilc_parse_join_bss_param` function, the TSF field of the `ies` structure is accessed after the RCU read-side critical section is unlocked. According to RCU usage rules, this is illegal. Reusing this pointer can lead to unpredictable behavior, including accessing memory that has been updated or causing use-after-free issues. This possible bug was identi... • https://git.kernel.org/stable/c/e556006de4ea93abe2b46cba202a2556c544b8b2 •

[0] The blamed change fixed another warning that is triggered when connect() is issued again for a socket whose connect()ed device has been unregistered. However, if the socket is just close()d without the 2nd connect(), the remaining bo->bcm_proc_read triggers unnecessary remove_proc_entry() in bcm_release().

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: block: fix potential invalid pointer dereference in blk_add_partition The blk_add_partition() function initially used a single if-condition (IS_ERR(part)) to check for errors when adding a partition. This was modified to handle the specific case of -ENXIO separately, allowing the function to proceed without logging the error in this case. However, this change unintentionally left a path where md_autodetect_dev() could be called without conf... • https://git.kernel.org/stable/c/b72053072c0bbe9f1cdfe2ffa3c201c185da2201 •

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: bpf, lsm: Add check for BPF LSM return value A bpf prog returning a positive number attached to file_alloc_security hook makes kernel panic. This happens because file system can not filter out the positive number returned by the LSM prog using IS_ERR, and misinterprets this positive number as a file pointer.
