CVE-2023-53676 (GCVE-0-2023-53676)

Vulnerability from cvelistv5 – Published: 2025-10-07 15:21 – Updated: 2026-01-05 10:21

Title

scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show()

Summary

In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Fix buffer overflow in lio_target_nacl_info_show() The function lio_target_nacl_info_show() uses sprintf() in a loop to print details for every iSCSI connection in a session without checking for the buffer length. With enough iSCSI connections it's possible to overflow the buffer provided by configfs and corrupt the memory. This patch replaces sprintf() with sysfs_emit_at() that checks for buffer boundries.

Title

rpl: Fix use-after-free in rpl_do_srh_inline().

Summary

In the Linux kernel, the following vulnerability has been resolved: rpl: Fix use-after-free in rpl_do_srh_inline(). Running lwt_dst_cache_ref_loop.sh in selftest with KASAN triggers the splat below [0]. rpl_do_srh_inline() fetches ipv6_hdr(skb) and accesses it after skb_cow_head(), which is illegal as the header could be freed then. Let's fix it by making oldhdr to a local struct instead of a pointer. [0]: [root@fedora net]# ./lwt_dst_cache_ref_loop.sh ...

CVE-2022-50490 (GCVE-0-2022-50490)

Vulnerability from cvelistv5 – Published: 2025-10-04 15:43 – Updated: 2025-10-04 15:43

Title

bpf: Propagate error from htab_lock_bucket() to userspace

Summary

In the Linux kernel, the following vulnerability has been resolved: bpf: Propagate error from htab_lock_bucket() to userspace In __htab_map_lookup_and_delete_batch() if htab_lock_bucket() returns -EBUSY, it will go to next bucket. Going to next bucket may not only skip the elements in current bucket silently, but also incur out-of-bound memory access or expose kernel memory to userspace if current bucket_cnt is greater than bucket_size or zero. Fixing it by stopping batch operation and returning -EBUSY when htab_lock_bucket() fails, and the application can retry or skip the busy batch as needed.
