ALSA-2026:2282 — Moderate: kernel security update

Affected: AlmaLinux:10: kernel-abi-stablelists, AlmaLinux:10: kernel-doc

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: Linux kernel: Memory corruption in Squashfs due to incorrect block size calculation (CVE-2025-38415) * kernel: vsock/vmci: Clear the vmci transport packet properly when initializing it (CVE-2025-38403) * kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling (CVE-2025-38730) * kernel: smb: client: let recv_done verify data_offset, data_length and remaining_data_length (CVE-2025-39933) * kernel: mptcp: Use __sk_dst_get() and dst_dev_rcu() in mptcp_active_enable() (CVE-2025-40133) * kernel: Linux kernel: Out-of-bounds write in fbdev can lead to privilege escalation, information disclosure, or denial of service. (CVE-2025-40304) * kernel: Linux kernel: Information disclosure and denial of service via out-of-bounds read in font glyph handling (CVE-2025-40322) * kernel: svcrdma: use rc_pageoff for memcpy byte offset (CVE-2025-68811)

fkie_cve-2025-68811

In the Linux kernel, the following vulnerability has been resolved:

svcrdma: use rc_pageoff for memcpy byte offset

svc_rdma_copy_inline_range added rc_curpage (page index) to the page base instead of the byte offset rc_pageoff. Use rc_pageoff so copies land within the current page.
