Affected files ============== The file(s) affected by this issue are: drivers/irqchip/irq-gic-v3.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/e824482e2c5edacc961b7dd30a92fd47606c3036 https://git.kernel.org/stable/c/8d884c08eeb83142a7173cb46bcff0434ec42cf1 https://git.kernel.org/stable/c/506a88a5bf261d76a5214c0338a320f2214c67ac https://git.kernel.org/stable/c/cc5984cf270b69d03f9f4b27063e535036c659e9 https://git.kernel.org/stable/c/c136c2924a59a399aa789858cfb320d481964fb7 https://git.kernel.org/stable/c/fa1ad9d4cc47ca2470cd904ad4519f05d7e43a2b
