CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-42313 – media: venus: fix use after free in vdec_close
https://notcve.org/view.php?id=CVE-2024-42313
In the Linux kernel, the following vulnerability has been resolved: media: venus: fix use after free in vdec_close There appears to be a possible use after free with vdec_close(). The firmware will add buffer release work to the work queue through HFI callbacks as a normal part of decoding. Randomly closing the decoder device from userspace during normal decoding can incur a read after free for inst. Fix it by cancelling the work in vdec_close. • https://git.kernel.org/stable/c/af2c3834c8ca7cc65d15592ac671933df8848115 https://git.kernel.org/stable/c/ad8cf035baf29467158e0550c7a42b7bb43d1db6 https://git.kernel.org/stable/c/72aff311194c8ceda934f24fd6f250b8827d7567 https://git.kernel.org/stable/c/4c9d235630d35db762b85a4149bbb0be9d504c36 https://git.kernel.org/stable/c/f8e9a63b982a8345470c225679af4ba86e4a7282 https://git.kernel.org/stable/c/da55685247f409bf7f976cc66ba2104df75d8dad https://git.kernel.org/stable/c/66fa52edd32cdbb675f0803b3c4da10ea19b6635 https://git.kernel.org/stable/c/6a96041659e834dc0b172dda4b2df512d •

https://notcve.org/view.php?id=CVE-2024-42312
In the Linux kernel, the following vulnerability has been resolved: sysctl: always initialize i_uid/i_gid Always initialize i_uid/i_gid inside the sysfs core so set_ownership() can safely skip setting them. Commit 5ec27ec735ba ("fs/proc/proc_sysctl.c: fix the default values of i_uid/i_gid on /proc/sys inodes.") added defaults for i_uid/i_gid when set_ownership() was not implemented. It also missed adjusting net_ctl_set_ownership() to use the same default values in case the computation of a better value failed. • https://git.kernel.org/stable/c/5ec27ec735ba0477d48c80561cc5e856f0c5dfaf https://git.kernel.org/stable/c/e83234d7ef237931148b4b17834dadf57eb46c12 https://git.kernel.org/stable/c/2cbf2af144f0cd08a3361c6299b2e6086b7d21d9 https://git.kernel.org/stable/c/2c7b50c7b1d036f71acd9a917a8cb0f9b6e43dab https://git.kernel.org/stable/c/7eb45a94c279dd5af4cafaa738ae93737517eef4 https://git.kernel.org/stable/c/14cc90952cef94bfa89a6b4a2f55fd9a70f50a16 https://git.kernel.org/stable/c/b2591c89a6e2858796111138c38fcb6851aa1955 https://git.kernel.org/stable/c/34a86adea1f2b3c3f9d864c8cce09dca6 •
