CVE-2026-99052

A flaw was found in the Linux kernel. When a Network File System version 4 NFSv4 share configured with security labels is mounted multiple times, the Security-Enhanced Linux SELinux subsystem fails to preserve native labeling flags on the reused filesystem. This flaw allows a local user to silent...

CVE-2026-99052

The Linux kernel contains a vulnerability where mounting an NFSv4 filesystem exported with security_label a second time can lead to a security regression. When the filesystem is remounted, sget_fc() returns the existing superblock, causing selinux_set_mnt_opts() to take an early exit without sett...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: NFSv4/pnfs: The key for the data server cache in the NFS version. The nfs4pnfsdsadd function keys the per-net data server cache on the multipath address set alone, and the struct nfs4pnfsds record does not specify a version...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: NFSv4/flexfiles: rejecting a zero filehandle-version count The fflayoutalloclseg function decodes the count of the filehandle-version array from the flexfiles layout body. This value is used as the count for kzallocobjs, and the...

CVE-2026-90151

A flaw was found in the Linux kernel's Network File System version 4 NFSv4 component. This vulnerability occurs when an NFSv4 client allocation fails, leaving a stale pointer to a freed client. A local attacker could potentially exploit this use-after-free condition by triggering a callback looku...

CVE-2026-90149

A flaw was found in the Linux kernel's NFSv4 Network File System version 4 flexfiles implementation. When an NFSv4.0 data server is used, two code paths incorrectly assume the client has a session, leading to a NULL pointer dereference. This issue can cause the kernel to crash, resulting in a...

CVE-2026-90148

A flaw was found in the Linux kernel's NFSv4 component. When the nfs4addlease function races with a delegation return, it can pass an incorrect, potentially null, argument to nfs4deletelease. This incorrect argument eventually leads to a null pointer dereference, which could allow a local attacke...

CVE-2026-90102

A flaw was found in the Linux kernel's NFSv4/pnfs component. The data server cache is incorrectly keyed only on the multipath address set, without considering the NFS version. This oversight allows different NFS versions to share the same internal data structure when two device IDs on one address...
