CVE-2022-26878

Posted by Sönke Huster on Mar 11Hi oss-security,

A memory leak in the VirtIO Bluetooth driver for Linux, which is included since v5.13, allows an attacker with access to the VirtIO counterpart of the driver
to create a DoS by sending invalid frames to the drivers interface.
Therefore, the driver must be in use.

This is fixed in 1d0688421449 [1], which was backported and thus
fixed in v5.16.3 [2] and v5.15.17 [3].

CVE-2022-26878 was assigned by MITRE.

Best,
Sönke

Comment 1 Alexander Bergmann 2022-03-11 14:46:01 UTC

The VirtIO Bluetooth driver is only available inside SLE-15-SP4 and there it is already fixed.

Closing again.

Comment 2 Takashi Iwai 2022-03-11 15:24:56 UTC

I updated the patch reference in SLE15-SP4 branch.
