Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: NFSv4.2: fix LAYOUTSTATS send buffer
 exhaustion encode_layoutstats_maxsz budgets XDR_QUADLEN(PNFS_LAYOUTSTATS_MAXSIZE), i.e. 256 bytes, for the
 layoutupdate4 body written by the layout driver. The flexfiles record can exceed that.
 ff_layout_encode_ff_layoutupdate() emits, per data server, a netaddr4, an nfs_fh4, two ff_io_latency4, an
 nfstime4 and a bool. A data server whose filehandle is NFS_MAXFHSIZE bytes long already accounts for 132
 of those bytes, and the two ff_io_latency4 at 64 bytes each, the nfstime4 and the bool add a further 144,
 so the body passes 256 bytes before the netaddr4 is encoded at all. encode_layoutstats() additionally
 writes the deviceid4 and the layoutupdate4 lou_type word, neither of which the macro accounts for. The
 filehandle and the address are both chosen by the server, through LAYOUTGET and GETDEVICEINFO, so it can
 drive the encoder past the end of the send buffer. xdr_reserve_space() returns NULL once that happens, and
 the two ff_layout_encode_io_latency() calls run with dss_info->mirror->lock held, so a NULL return there
 leaves the lock permanently held. Raise PNFS_LAYOUTSTATS_MAXSIZE to 384 so that the record fits inside the
 reservation. (CVE-2026-90103)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
