Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains an issue where the return value from change memory common is not properly propagated. The rodata=on security measure requires protection of the linear map alias during vmalloc operations with set memory ro or set memory rox. Failure to propagate errors from these calls can lead to issues, particularly after commit a166563e7ec3 ("arm64: mm: support large block mapping when rodata=full"). This can result in suppressed errors and potential instability.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
