In the Linux kernel, the following vulnerability has been resolved: arm64: ftrace: consistently handle PLTs. Sometimes it is necessary to use a PLT entry to call an ftrace trampoline. This is handled by ftracemakecall and ftracemakenop, with each having almost identical logic, but this is not...

CVE-2025-21789

CVE-2025-21789 concerns the Linux kernel IP checksum code. The issue arises from the LoongArch path where commit 69e3a6aa6be2 introduced a negative-length OoB access/undefined shift in the IP checksum, which could trigger an out-of-bounds read under certain conditions. A corresponding ARM64 fix w...
