Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfsd: never defer requests during idmap lookup During the decoding of v4 request compound arguments, certain operations e.g., SETATTR can trigger idmap lookup upcalls. When the responses to these upcalls are delayed beyond the...

kernel: NFSD: Avoid calling OPDESC() with ops->opnum == OP_ILLEGAL

In the Linux kernel, the following vulnerability has been resolved: NFSD: Avoid calling OPDESC with ops-opnum == OPILLEGAL OPDESC simply indexes into nfsd4ops by the op's operation number, without range checking that value. It assumes callers are careful to avoid calling it with an out-of-bounds...

kernel: nfsd4: bug in read_buf

Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow remote attackers to cause a denial of service panic or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the readbuf and...
