PHP 8.5.11 OOM and Stale State Remote Code Execution

PHP versions before 8.2.35, 8.3.36, 8.4.27, and 8.5.12 contain OOM-corruption and stale-global-state flaws that can lead to unauthenticated remote code execution. This proof of concept targets affected session upload progress handling. https://packetstorm.news/download/236977...

CVE-2026-79976

The MCTP-over-I2C+GPIO target binding in subsys/pmci/mctp/mctpi2cgpiotarget.c emulates a small pseudo-register file, where the bus controller first writes a register number and then writes or reads payload bytes. The selected register b-regaddr and the data-phase flag b-rxtx were never cleared wh...

UBUNTU-CVE-2026-109619

request-owned internal state can survive after its backing memory has been freed. A later request handled by the same worker may use that stale state before normal initialization resets it...

CVE-2026-109619

PHP has various global state that temporarily points into request memory. In some scenarios, global state may not be correctly reset, or may be repopulated after being reset. The global state may then refer to request memory even after it has been freed. Subsequent requests may read or branch on...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...

In the Linux kernel, the following vulnerability has been resolved: ocfs2/cluster: keep heartbeat local node stable o2nmnodelocalstore handles local=0 by stopping o2net and setting cllocalnode to O2NMINVALIDNODENUM, but it leaves clhaslocal set. That stale state makes o2nmthisnode return 255,...

CVE-2026-89754

A flaw was found in the Linux kernel's memory management mm/pagewalk component. An issue in the walkpmdrange function, where a stale walk-action state is not properly reset, can lead to duplicate walk callbacks. A local attacker could exploit this to trigger an out-of-bounds write, potentially...

UBUNTU-CVE-2026-89521

In the Linux kernel, the following vulnerability has been resolved: sched/core: Handle picktask releasing the rq lock Core scheduling's picknexttask breaks when a -picktask implementation can release the rq lock. The selection state derived on entry is only valid while the lock is held...

CVE-2026-89754

In the Linux kernel, the following vulnerability has been resolved: mm/pagewalk: fix stale walk-action escaping walkpmdrange If -pmdentry sets walk-action = ACTIONAGAIN, the pmdnone check is retried. The PMD entry may be cleared at the point of retry. In this case, if walk-ops-installpte is not...

CVE-2026-80989

CVE-2026-80989 affects the Linux kernel Thunderbolt networking subsystem (net: thunderbolt).
