perm check and set-uid/gid usage\n\nWhen opening a file for exec via do_filp_open(), permission checking is\ndone against the file's metadata at that moment, and on success, a file\npointer is passed back. Much later in the execve() code path, the file\nmetadata (specifically mode, uid, and gid) is used to determine if/how\nto set the uid and gid. However, those values may have changed since the\npermissions check, meaning the execution may gain unintended privileges.\n\nFor example, if a file could change permissions from executable and not\nset-id:\n\n---------x 1 root root 16048 Aug  7 13:16 target\n\nto set-id and non-executable:\n\n---S------ 1 root root 16048 Aug  7 13:16 target\n\nit is possible to gain root privileges when execution should have been\ndisallowed.\n\nWhile this race condition is rare in real-world scenarios, it has been\nobserved (and proven exploitable) when package managers are updating\nthe setuid bits of installed programs. Such files start with being\nworld-executable but then are adjusted to be group-exec with a set-uid\nbit. For example, \"chmod o-x,u+s target\" makes \"target\" executable only\nby uid \"root\" and gid \"cdrom\", while also becoming setuid-root:\n\n-rwxr-xr-x 1 root cdrom 16048 Aug  7 13:16 target\n\nbecomes:\n\n-rwsr-xr-- 1 root cdrom 16048 Aug  7 13:16 target\n\nBut racing the chmod means users without group \"cdrom\" membership can\nget the permission to execute \"target\" just before the chmod, and when\nthe chmod finishes, the exec reaches brpm_fill_uid(), and performs the\nsetuid to root, violating the expressed authorization of \"only cdrom\ngroup members can setuid to root\".\n\nRe-check that we still have execute permissions in case the metadata\nhas changed. It would be better to keep a copy from the perm-check time,\nbut until we can do that refactoring, the least-bad option is to do a\nfull inode_permission() call (under inode lock). It is understood that\nthis is safe against dead-locks, but hardly optimal.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.ppc64le","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.s390x","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2024-43882","url":"https://www.suse.com/security/cve/CVE-2024-43882"},{"category":"external","summary":"SUSE Bug 1229503 for CVE-2024-43882","url":"https://bugzilla.suse.com/1229503"},{"category":"external","summary":"SUSE Bug 1229504 for CVE-2024-43882","url":"https://bugzilla.suse.com/1229504"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.ppc64le","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.s390x","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7,"baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.ppc64le","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.s390x","SUSE Linux Enterprise Live Patching 12 SP5:kgraft-patch-4_12_14-122_216-default-16-2.1.x86_64"]}],"threats":[{"category":"impact","date":"2025-05-19T20:39:22Z","details":"important"}],"title":"CVE-2024-43882"},{"cve":"CVE-2024-50115","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2024-50115"}],"notes":[{"category":"general","text":"In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: nSVM: Ignore nCR3[4:0] when loading PDPTEs from memory\n\nIgnore nCR3[4:0] when loading PDPTEs from memory for nested SVM, as bits\n4:0 of CR3 are ignored when PAE paging is used, and thus VMRUN doesn't\nenforce 32-byte alignment of nCR3.\n\nIn the absolute worst case scenario, failure to ignore bits 4:0 can result\nin an out-of-bounds read, e.g. if the target page is at the end of a\nmemslot, and the VMM isn't using guard pages.\n\nPer the APM:\n\n  The CR3 register points to the base address of the page-directory-pointer\n  table.
