CVE-2026-22988

CVE-2026-22988 affects the Linux kernel’s arp handling, specifically the assumption that skb->head remains unchanged after dev_hard_header() in arp_create(). The issue arises when a recent commit altered skb->head, breaking that assumption. The publicly provided description and OpenVAS/Ness...

CVE-2022-50839

Summary (CVE-2022-50839) The issue is in the Linux kernel’s jbd2 journaling subsystem. When a buffer isn’t uptodate, jbd2_fc_wait_bufs returns -EIO without updating journal->j_fc_off, and jbd2_fc_release_bufs may release the buffer head from j_fc_off - 1 if bh is NULL, causing a buffer head re...
