In the Linux kernel, the following vulnerability has been resolved: crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree Annotating a local pointer variable, which will be assigned with the kmalloc-family functions, with the `__cleanup(kfree)` attribute will make the address of the local variable, rather than the address returned by kmalloc, passed to kfree directly and lead to a crash due to invalid deallocation of stack address. According to other places in the repo, the correct usage should be `__free(kfree)`. The code coincidentally compiled because the parameter type `void *` of kfree is compatible with the desired type `struct { ... } **`.

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:70459 advisory.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree Annotating a local pointer variable,     which will be assigned with the kmalloc-family functions, with the `__cleanup(kfree)` attribute will make     the address of the local variable, rather than the address returned by kmalloc, passed to kfree directly     and lead to a crash due to invalid deallocation of stack address.
