| 2024-10-21 | CVE-2024-49987 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpftool: Fix undefined behavior in qsort(NULL, 0, ...) When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). | 5.5 |
| 2024-10-21 | CVE-2024-49988 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ksmbd: add refcnt to ksmbd_conn struct When sending an oplock break request, opinfo->conn is used, But freed ->conn can be used on multichannel. This patch add a reference count to the ksmbd_conn struct so that it can be freed when it is no longer used. | 5.5 |
| 2024-10-21 | CVE-2024-49989 | Double Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: fix double free issue during amdgpu module unload Flexible endpoints use DIGs from available inflexible endpoints, so only the encoders of inflexible links need to be freed. Otherwise, a double free issue may occur when unloading the amdgpu module.

| 2024-10-21 | CVE-2024-49994 | Integer Overflow or Wraparound vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: block: fix integer overflow in BLKSECDISCARD I independently rediscovered commit 22d24a544b0d49bbcbd61c8c0eaf77d3c9297155 block: fix overflow in blk_ioctl_discard() but for secure erase. Same problem: uint64_t r[2] = {512, 18446744073709551104ULL}; ioctl(fd, BLKSECDISCARD, r); will enter near infinite loop inside blkdev_issue_secure_erase(): a.out: attempt to access beyond end of device loop0: rw=5, sector=3399043073, nr_sectors = 1024 limit=2048 bio_check_eod: 3286214 callbacks suppressed | 5.5 |
| 2024-10-21 | CVE-2024-49995 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tipc: guard against string buffer overrun Smatch reports that copying media_name and if_name to name_parts may overwrite the destination. .../bearer.c:166 bearer_name_validate() error: strcpy() 'media_name' too large for 'name_parts->media_name' (32 vs 16) .../bearer.c:167 bearer_name_validate() error: strcpy() 'if_name' too large for 'name_parts->if_name' (1010102 vs 16) This does seem to be the case so guard against this possibility by using strscpy() and failing if truncation occurs. Introduced by commit b97bf3fd8f6a ("[TIPC] Initial merge") Compile tested only. | 7.8 |
