OESA-2023-1276 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: The specific flaw exists within the DPT I2O Controller driver. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to...

kernel: driver core: Fix wait_for_device_probe() & deferred_probe_timeout interaction

In the Linux kernel, the following vulnerability has been resolved: driver core: Fix waitfordeviceprobe & deferredprobetimeout interaction Mounting NFS rootfs was timing out when deferredprobetimeout was non-zero 1. This was because ipautoconfig initcall times out waiting for the network interfac...

kernel: iavf: Fix reset error handling

A deadlock condition exists in the linux kernel such that when calling iavfclose in iavfresettask error handling,doing so can lead to double call of napidisable thereby leading to a denial of service due to the deadlock...

kernel: Kernel: Denial of Service via recursive deadlock in L2TP tunnel registration

A flaw was found in the kernel. A local user can exploit this vulnerability by passing a pppol2tp socket file descriptor as a UDP socket file descriptor during L2TP tunnel registration. This can cause a recursive deadlock, leading to a denial of service DoS on the system...

kernel: ext4: don't set up encryption key during jbd2 transaction

A flaw exists in the ext4 filesystem implementation in the Linux kernel such that the function ext4unlink extended a journaling transaction too far so that it included a call to ext4findentry. However, ext4findentry may need to set up a directory’s encryption key — which can cause a deadlock when...
