CVE-2026-72025

In the Linux kernel, the following vulnerability has been resolved: s390/monwriter: Reject buffer reuse with different data length When data buffers are reused, e.g. for interval sample records, the first record determines the data length, and the size of the buffer for user copy. Current monwrit...

CVE-2026-72023

CVE-2026-72023 affects the Linux kernel’s octeontx2-pf driver. otx2_init_hw_resources() allocates SQ aura/pool resources before later setup steps, and on failure err_free_sq_ptrs frees only SQB pages, leaving per-SQ sqb_ptrs behind. The documented fix uses otx2_free_sq_res() for the SQ unwind pat...

CVE-2026-72020

CVE-2026-72020 affects the Linux kernel IP Virtual Server (IPVS) code. A bug in ip_vs_conn_new() caused only two ip_vs_seq members (in_seq and out_seq) to be reset, leaving init_seq and previous_delta uninitialized. For connections learned from a sync message, flags and data could be inconsistent...
