Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A potential deadlock issue has been resolved in the Linux kernel, specifically in the exfat file system. The problem occurs when accessing a file with more entries than ES MAX ENTRY NUM, causing the bh-array to be allocated with GFP KERNEL, which can lead to a deadlock for sbi->s lock between two processes. This issue can happen in the following scenarios:
CPU0 and CPU1 are executing different threads, with CPU0 running kswapd and CPU1 running exfat iterate, both trying to lock sbi->s lock.
To fix this issue, the bh-array should be allocated with GFP NOFS.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
