• Severity: unknown
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days

Description

In the Linux kernel, the following vulnerability has been resolved: xfs: fix unit conversions in per_binval computation LOLLM noticed that we're doing the unit conversion in the per_binval computation backwards -- xfs_buf_inval_log_space's second parameter is supposed to be in bytes, but max_binval is in units of fsblocks. Hence the conversion should be FSB -> B, not the other way around.

Affected products

• Linux kernel: 6.18 — fixed in 7.3

How to fix

Upgrade to a fixed version: Linux kernel 7.3. Check the vendor advisory for mitigations.
