Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: proc: Fixed a UAF in procgetinode. Fixed a race condition between rmmod and the instantiation of /proc/XXX’s inode. The bug is that pde-procops does not belong to /proc; it belongs to a module. Therefore, dereferencing it afte...

kernel: proc: fix UAF in proc_get_inode()

In the Linux kernel, the following vulnerability has been resolved: proc: fix UAF in procgetinode Fix race between rmmod and /proc/XXX's inode instantiation. The bug is that pde-procops don't belong to /proc, it belongs to a module, therefore dereferencing it after /proc entry has been registered...

CVE-2026-43063 xfs: don't irele after failing to iget in xfs_attri_recover_work

In the Linux kernel, the following vulnerability has been resolved: xfs: don't irele after failing to iget in xfsattrirecoverwork xlogrecoveryiget never set @ip to a valid pointer if they return an error, so this irele will walk off a dangling pointer. Fix that...

CVE-2025-68820

A NULL pointer dereference vulnerability was found in the Linux kernel's ext4 filesystem extended attribute handling. When ext4getinodeloc fails with an error such as -EFSCORRUPTED, the iloc.bh buffer head remains NULL. The ext4xattrinodedecrefall function lacks error checking and proceeds to cal...

CVE-2025-68820

In the Linux kernel, the following vulnerability has been resolved: ext4: xattr: fix null pointer deref in ext4rawinode If ext4getinodeloc fails e.g. if it returns -EFSCORRUPTED, iloc.bh will remain set to NULL. Since ext4xattrinodedecrefall lacks error checking, this will lead to a null pointer...
