In the Linux kernel, the following vulnerability has been resolved:

media: vivid: fix compose size exceed boundary

syzkaller found a bug:

This is because we forget to check boundary after adjust compose->height int V4L2_SEL_TGT_CROP case. Add v4l2_rect_map_inside() to fix this problem for this case.

OESA-2024-2257 — kernel security update

Affected: openEuler:22.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): In the Linux kernel, the following vulnerability has been resolved: i40e: Fix kernel crash during module removal The driver incorrectly frees client instance and subsequent i40e module removal leads to kernel crash. Reproducer: 1. Do ethtool offline test followed immediately by another one host# ethtool -t eth0 offline; ethtool -t eth0 offline 2. Remove recursively irdma module that also removes i40e module host# modprobe -r irdma Result: [ 8675.035651] i40e 0000:3d:00.0 eno1: offline testing starting [ 8675.193774] i40e 0000:3d:00.0 eno1: testing finished [ 8675.201316] i40e 0000:3d:00.0 eno1: offline testing starting [ 8675.358921] i40e 0000:3d:00.0 eno1: testing finished [ 8675.496921] i40e 0000:3d:00.0: IRDMA hardware initialization FAILED init_state=2 status=-110 [ 8686.188955] i40e 0000:3d:00.1: i40e_ptp_stop: removed PHC on eno2 [ 8686.943890] i40e 0000:3d:00.1: Deleted LAN device PF1 bus=0x3d dev=0x00 func=0x01 [ 8686.952669] i40e 0000:3d:00.0: i40e_ptp_stop: removed PHC on eno1 [ 8687.761787] BUG: kernel NULL pointer dereference, address: 0000000000000030 [ 8687.768755] #PF: supervisor read access in kernel mode [ 8687.773895] #PF: error_code(0x0000) - not-present page [ 8687.779034] PGD 0 P4D 0 [ 8687.781575] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 8687.785935] CPU: 51 PID: 172891 Comm: rmmod Kdump: loaded Tainted: G W I 5.19.0+ #2 [ 8687.794800] Hardware name: Intel C…
