Last modified: 2024-07-01 16:07:55 UTC
In the Linux kernel, the following vulnerability has been resolved: crypto: virtio/akcipher - Fix stack overflow on memcpy sizeof(struct virtio_crypto_akcipher_session_para) is less than sizeof(struct virtio_crypto_op_ctrl_req::u), copying more bytes from stack variable leads stack overflow. Clang reports this issue by commands: make -j CC=clang-14 mrproper >/dev/null 2>&1 make -j O=/tmp/crypto-build CC=clang-14 allmodconfig >/dev/null 2>&1 make -j O=/tmp/crypto-build W=1 CC=clang-14 drivers/crypto/virtio/ virtio_crypto_akcipher_algs.o References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2024-26753 https://www.cve.org/CVERecord?id=CVE-2024-26753 https://git.kernel.org/stable/c/37077ed16c7793e21b005979d33f8a61565b7e86 https://git.kernel.org/stable/c/62f361bfea60c6afc3df09c1ad4152e6507f6f47 https://git.kernel.org/stable/c/b0365460e945e1117b47cf7329d86de752daff63 https://git.kernel.org/stable/c/c0ec2a712daf133d9996a8a1b7ee2d4996080363 https://git.kernel.org/stable/c/ef1e47d50324e232d2da484fe55a54274eeb9bc1 https://bugzilla.redhat.com/show_bug.cgi?id=2273217 https://git.kernel.org/pub/scm/linux/security/vulns.git/plain/cve/published/2024/CVE-2024-26753.mbox
SLE15-SP6-GA and stable contain both offending and fixing commit, and no other branch is affected. So I guess only changelog update is needed
