postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...

CVE-2026-53334

The CVE-2026-53334 issue affects the Linux kernel DAMON subsystem, specifically mm/damon/reclaim and mm/damon/lru_sort. The root cause is a failure to handle damon_ctx allocations: if the kdamond damon_ctx allocation fails, code may dereference a NULL ctx in damon_commit_ctx(), leading to potenti...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...
