In the Linux kernel, the following vulnerability has been resolved: tracepoint: balance regfunc on funcadd failure in tracepointaddfunc When a tracepoint goes through the 0 - 1 transition, tracepointaddfunc invokes the subsystem's ext-regfunc before attempting to install the new probe via funcadd...
CVE-2026-46196
In the Linux kernel, the following vulnerability has been resolved: tracepoint: balance regfunc on funcadd failure in tracepointaddfunc When a tracepoint goes through the 0 - 1 transition, tracepointaddfunc invokes the subsystem's ext-regfunc before attempting to install the new probe via funcadd...
CVE-2026-46196
CVE-2026-46196 describes a Linux kernel tracepoint regression: during a 0→1 transition, tracepoint_add_func() calls ext->regfunc() before installing a probe, and if func_add() fails (e.g., -ENOMEM), it previously did not call ext->unregfunc(), leaving behind side effects. The fix mirrors th...
CVE-2026-46196 tracepoint: balance regfunc() on func_add() failure in tracepoint_add_func()
In the Linux kernel, the following vulnerability has been resolved: tracepoint: balance regfunc on funcadd failure in tracepointaddfunc When a tracepoint goes through the 0 - 1 transition, tracepointaddfunc invokes the subsystem's ext-regfunc before attempting to install the new probe via funcadd...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the tracepoint module. In this case, when funcadd fails, the matching unregfunc function is not...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: f2fs: Fixed a null pointer panic in the tracepoint of replaceatomicwriteblock. A kernel panic occurs when oldaddr is NULL. https://bugzilla.kernel.org/showbug.cgi?id=217266 BUG: Null pointer dereferencing in the kernel; address:...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: f2fs: fixed the assignment logic of iocb. Commit 18ae8d12991b “f2fs: shows more DIO information at the tracepoint” introduced the iocb field in the ‘f2fsdirectIOenter’ trace event. It only assigns the pointer and then accesses...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: slab: fixed the context check for kmallocnolock in the PREEMPTRT kernel mode. In PREEMPTRT kernels, locallock acts as a sleeping lock. The current check in kmallocnolock only verifies that the context does not match NMI or hard I...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference exists in the smc msg event tracepoint class, which is shared by smc tx sendmsg and smc rx recvmsg. The issue occurs because the system unconditionally...
EUVD-2026-27643
In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: get correct superblock from dentry in event btrfssyncfile If overlay is used on top of btrfs, dentry-dsb translates to overlay's super block and fsid assignment will lead to a crash. Use fileinodefile-isb to...
AZL-83357 CVE-2026-31453 affecting package kernel for versions less than 6.6.134.1-2
In the Linux kernel, the following vulnerability has been resolved: xfs: avoid dereferencing log items after push callbacks After xfsaildpushitem calls ioppush, the log item may have been freed if the AIL lock was dropped during the push. Background inode reclaim or the dquot shrinker can free th...
