CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2023-3776 – Use-after-free in Linux kernel's net/sched: cls_fw component
https://notcve.org/view.php?id=CVE-2023-3776
A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f. A use-after-free vulnerability was found in fw_set_parms in net/sched/cls_fw.c in network scheduler sub-component in the Linux Kernel. This issue occurs due to a missing sanity check during cleanup at the time of failure, leading to a misleading reference. This may allow a local attacker to gain local privilege escalation. • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html http://packetstormsecurity.com/files/175963/Kernel-Live-Patch-Security-Notice-LSN-0099-1.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=0323bce598eea038714f941ce2b22541c46d488f https://kernel.dance/0323bce598eea038714f941ce2b22541c46d488f https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.neta • CWE-416: Use After Free •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2023-3611 – Out-of-bounds write in Linux kernel's net/sched: sch_qfq component
https://notcve.org/view.php?id=CVE-2023-3611
An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. An out-of-bounds memory write flaw was found in qfq_change_agg in net/sched/sch_qfq.c in the Traffic Control (QoS) subsystem in the Linux kernel. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3e337087c3b5805fe0b8a46ba622a962880b5d64 https://kernel.dance/3e337087c3b5805fe0b8a46ba622a962880b5d64 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230908-0002 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/C • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2023-3610
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. A use-after-free vulnerability was found in the netfilter: nf_tables component in the Linux kernel due to a missing error handling in the abort path of NFT_MSG_NEWRULE. This flaw allows a local attacker with CAP_NET_ADMIN access capability to cause a local privilege escalation problem. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=4bedf9eee016286c835e3d8fa981ddece5338795 https://kernel.dance/4bedf9eee016286c835e3d8fa981ddece5338795 https://lists.debian.org/debian-lts-announce/2023/08/msg00001.html https://security.netapp.com/advisory/ntap-20230818-0005 https://www.debian.org/security/2023/dsa-5461 https://access.redhat.com/security/cve/CVE-2023-3610 https://bugzilla.redhat.com/show_bug.cgi?id=2225198 • CWE-416: Use After Free •
