In the Linux kernel, the following vulnerability has been resolved: drm: Replace old pointer to new idr Commit 5e28b7b94408 introduced a logical error by failing to replace the newly generated IDR pointer to old id's pointer at the correct location within the "change handle" logic; this resulted ...

CVE-2026-52923

In the Linux kernel, the following vulnerability has been resolved: ipc: limit nextid allocation to the valid ID range The checkpoint/restore sysctl path can request the next SysV IPC id through ids-nextid. ipcidralloc currently forwards that request to idralloc with an open-ended upper bound. If...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ICE: Avoid crashes due to unnecessary IDA frees. In the “remove path”, there is an attempt to free the auxidx IDA, regardless of whether it was allocated or not. This could potentially cause a crash when unloading the driver on...

CVE-2023-54206

CVE-2023-54206 affects the Linux kernel net/sched flower filter initialization. The root cause is a race where idr initialization was moved too early in fl_change(), allowing concurrent access to a filter still being initialized, risking a NULL pointer dereference. The published mitigations descr...

CVE-2023-54147

In the Linux kernel, the following vulnerability has been resolved: media: platform: mtk-mdp3: Add missing check and free for idaalloc Add the check for the return value of the idaalloc in order to avoid NULL pointer dereference. Moreover, free allocated "ctx-id" if mdpm2mopen fails later in orde...

In the Linux kernel, the following vulnerability has been resolved: PCI: Fix use-after-free in pcibusreleasedomainnr Commit c14f7ccc9f5d "PCI: Assign PCI domain IDs by idaalloc" introduced a use-after-free bug in the bus removal cleanup. The issue was found with kfence: 19.293351 BUG: KFENCE:...

DEBIAN-CVE-2024-58078

In the Linux kernel, the following vulnerability has been resolved: misc: miscminoralloc to use ida for all dynamic/misc dynamic minors miscminoralloc was allocating id using ida for minor only in case of MISCDYNAMICMINOR but miscminorfree was always freeing ids using idafree causing a mismatch a...

kernel: dax: Fix dax_mapping_release() use after free

A use-after-free vulnerability was found in the Linux kernel's device-dax subsystem during mapping object cleanup. When removing a dax region provider, the child daxmapping objects attempt to free their ID allocator after the parent devdax object has already been released. This causes idafree to...
