Low risk6th percentile - higher than 6% of all known CVEs
Summary
In the Linux kernel, the dm_early_create function has a bug where it attempts to free an already used table when dm_resume fails. The table was already instantiated with dm_swap_table, and the code tries to destroy it again, which may lead to incorrect behavior. The fix skips the dm_table_destroy call in this case.
Risk Assessment
The risk includes potential memory corruption or malfunction of the device mapper, which could lead to system crashes or instability.
Recommendation
It is recommended to apply the Linux kernel patch that removes the unnecessary dm_table_destroy call in the dm_resume error path as soon as possible.
