In the Linux kernel, the following vulnerability has been resolved: crypto:
rsa - add a check for allocation failure Static checkers insist that the
mpi_alloc() allocation can fail so add a check to prevent a NULL
dereference. Small allocations like this can’t actually fail in current
kernels, but adding a check is very simple and makes the static checkers
happy.
Notes
| Author | Note |
|---|---|
| Priority reason: NULL pointer dereference on memory allocation failure which is very unlikely for an attacker to be able to influence and hence cause. | |
| rodrigo-zaiden | USN-6765-1 for linux-oem-6.5 wrongly stated that this CVE was fixed in version 6.5.0-1022.23. The mentioned notice was revoked and the state of the fix for linux-oem-6.5 was recovered to the previous state. |
