CVE-2026-52930

The CVE concerns the Linux kernel’s shared memory (ipc/shm) subsystem, specifically the orphan cleanup path. The vulnerability arises because shm_destroy_orphaned() traverses shm IDs under shm_ids(ns).rwsem but shm_nattch can be updated while holding shm_perm.lock, and attach paths may modify it ...

Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-002393)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-002393 advisory. Multiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial of service use-after-free and system crash or possibly ha...

The vulnerability of the do_shmat function in the ipc/shm.c component of the Linux operating system’s kernel, which stems from insufficient validation of input data, allows a privileged user to circumvent existing security restrictions.

The vulnerability of the doshmat function in the ipc/shm.c component of the Linux operating system’s kernel is related to insufficient validation of input data. Exploiting this vulnerability could allow an attacker to circumvent existing security restrictions...

Linux kernel local security bypass vulnerability (CNVD-2017-02602)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the 'doshmat' function in the ipc/shm.c file in Linux kernel versions 4.9.12 and earlier. A local attacker can exploit this vulnerability to...

DEBIAN-CVE-2017-5669

The doshmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget a...

kernel: ipc/shm.c: reading uninitialized stack memory

The copyshmidtouser function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the "old shm interface."...
