CVE-2026-23388

CVE-2026-23388 concerns the Linux kernel Squashfs subsystem. A corrupted index lookup can yield a negative metadata block offset, leading to an out-of-bounds access in squashfs_copy_data via squashfs_read_metadata. The issue is resolved by adding a metadata offset range check in squashfs_read_met...

CVE-2026-23389

CVE-2026-23389 (Linux kernel ice component) : The issue is a memory leak in ice_set_ringparam() where tx_rings and xdp_rings are allocated before rx_rings. If rx_rings allocation fails, the code jumps to a done path that leaks both tx_rings and xdp_rings; if a per-Rx ring setup fails, code may ju...

CVE-2026-23393

CVE-2026-23393 – Linux kernel (bridge/cfm) race fix : A race during peer MEP deletion could occur because br_cfm_frame_rx() could re-schedule ccm_rx_dwork while peer_mep is freed under RCU, risking use-after-free.
