In the Linux kernel, the following vulnerability has been resolved: x86/kexec: Disable KCOV instrumentation after load_segments() The load_segments() function changes segment registers, invalidating GS base (which KCOV relies on for per-cpu data). When CONFIG_KCOV is enabled, any subsequent instrumented C code call (e.g. native_gdt_invalidate()) begins crashing the kernel in an endless loop. To reproduce the problem, it's sufficient to do kexec on a KCOV-instrumented kernel: $ kexec -l /boot/otherKernel $ kexec -e The real-world context for this problem is enabling crash dump collection in syzkaller. For this, the tool loads a panic kernel before fuzzing and then calls makedumpfile after the panic. This workflow requires both CONFIG_KEXEC and CONFIG_KCOV to be enabled simultaneously. Adding safeguards directly to the KCOV fast-path (__sanitizer_cov_trace_pc()) is also undesirable as it would introduce an extra performance overhead. Disabling instrumentation for the individual functions would be too fragile, so disable KCOV instrumentation for the entire machine_kexec_64.c and physaddr.c. If coverage-guided fuzzing ever needs these components in the future, other approaches should be considered. The problem is not relevant for 32 bit kernels as CONFIG_KCOV is not supported there.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8906-1 advisory.

    It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB)     invalidation before memory writes made through the invalidated translation were globally observed. A local     attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing     memory protections or escalating privileges. (CVE-2025-10263)

    Several security issues were discovered in the Linux kernel. An attacker could possibly use these to     compromise the system. This update corrects flaws in the following subsystems:

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.94-1.

    We recommend that you upgrade your linux packages.

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - x86/kexec: Disable KCOV instrumentation after load_segments() The load_segments() function changes segment     registers, invalidating GS base (which KCOV relies on for per-cpu data). When CONFIG_KCOV is enabled, any     subsequent instrumented C code call (e.g. native_gdt_invalidate()) begins crashing the kernel in an     endless loop. To reproduce the problem, it's sufficient to do kexec on a KCOV-instrumented kernel: $ kexec
    -l /boot/otherKernel $ kexec -e The real-world context for this problem is enabling crash dump collection     in syzkaller. For this, the tool loads a panic kernel before fuzzing and then calls makedumpfile after the     panic. This workflow requires both CONFIG_KEXEC and CONFIG_KCOV to be enabled simultaneously. Adding     safeguards directly to the KCOV fast-path (__sanitizer_cov_trace_pc()) is also undesirable as it would     introduce an extra performance overhead. Disabling instrumentation for the individual functions would be     too fragile, so disable KCOV instrumentation for the entire machine_kexec_64.c and physaddr.c. If     coverage-guided fuzzing ever needs these components in the future, other approaches should be considered.
    The problem is not relevant for 32 bit kernels as CONFIG_KCOV is not supported there. [ bp: Space out     comment for better readability. ] (CVE-2026-43331)

Note that Nessus relies on the presence of the package as reported by the vendor.
