| 2024-10-21 | CVE-2024-49861 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf: Fix helper writes to read-only maps Lonial found an issue that despite user- and BPF-side frozen BPF map (like in case of .rodata), it was still possible to write into it from a BPF program side through specific helpers having ARG_PTR_TO_{LONG,INT} as arguments. In check_func_arg() when the argument is as mentioned, the meta->raw_mode is never set. | 7.1 |
| 2024-10-21 | CVE-2024-47678 | Information Exposure Through Discrepancy vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: icmp: change the order of rate limits ICMP messages are ratelimited : After the blamed commits, the two rate limiters are applied in this order: 1) host wide ratelimit (icmp_global_allow()) 2) Per destination ratelimit (inetpeer based) In order to avoid side-channels attacks, we need to apply the per destination check first. This patch makes the following change : 1) icmp_global_allow() checks if the host wide limit is reached. But credits are not yet consumed. | 5.5 |
| 2024-10-21 | CVE-2024-47682 | Off-by-one Error vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix off-by-one error in sd_read_block_characteristics() Ff the device returns page 0xb1 with length 8 (happens with qemu v2.x, for example), sd_read_block_characteristics() may attempt an out-of-bounds memory access when accessing the zoned field at offset 8. | 7.8 |

Do proper cleanup using gid_table_cleanup_one before returning the err in order to fix the issue.

| 2024-10-21 | CVE-2024-47703 | Unspecified vulnerability in Linux Kernel 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. Given that hook file_alloc_security never returned positive number before the introduction of BPF LSM, and other BPF LSM hooks may encounter similar issues, this patch adds LSM return value check in verifier, to ensure no unexpected value is returned. | 5.5 |
