CVE-2023-54121

CVE-2023-54121 affects the Linux kernel's btrfs extent_map handling. The bug in btrfs_drop_extent_map_range can miscalculate the length when skipping a pinned extent, leading to a faulty split of the next extent and creating an invalid extent_map that may overlap other entries and disrupt block c...

CVE-2025-68744

CVE-2025-68744 is a Linux kernel vulnerability affecting BPF maps. The issue arises from not freeing memory for BPF_KPTR_{REF,PERCPU} fields when updating certain lru_percpu_hash maps, potentially causing references to remain after map destruction. The root cause, as described in the initial CVE ...
