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: svcrdma: Reject Read lists that exceed
the page budget Individual Read segment lengths are validated at decode time, but nothing prevents a
requester from sending multiple segments whose cumulative length exceeds the rq_pages array budget. When
one segment fills the page array exactly, the runtime guard in svc_rdma_build_read_segment() is bypassed
because len reaches zero. A subsequent segment then accesses the NULL sentinel slot at
rq_pages[rq_maxpages], resulting in a NULL pointer dereference during DMA mapping. Accumulate pages across
all Read segments and reject the message at decode time when the total would overflow the page budget.
(CVE-2026-89528)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
