Summary
Moderate: kernel security update
Details

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)
