| IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.1, and 11.5 is vulnerable to a denial of service through a specially crafted federated query on specific federation objects. IBM X-Force ID: 252048. | |||||
| CVE-2023-5717 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer. We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. | |||||
| CVE-2023-5197 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 6.6 MEDIUM |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Addition and removal of rules from chain bindings within the same transaction causes leads to use-after-free. We recommend upgrading past commit f15f29fd4779be8a418b66e9d52979bb6d6c2325. | |||||
| CVE-2023-46862 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 4.7 MEDIUM |
| An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. | |||||
| CVE-2023-46813 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 7.0 HIGH |
| An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it. | |||||
| CVE-2023-45863 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 6.4 MEDIUM |
| An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker can trigger a race condition that results in a fill_kobj_path out-of-bounds write. | |||||
| CVE-2023-35827 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 7.0 HIGH |
| An issue was discovered in the Linux kernel through 6.3.8. A use-after-free was found in ravb_remove in drivers/net/ethernet/renesas/ravb_main.c. | |||||
| CVE-2023-34324 | 2 Linux, Xen | 2 Linux Kernel, Xen | 2024-01-11 | N/A | 4.9 MEDIUM |
| Closing of an event channel in the Linux kernel can result in a deadlock. This happens when the close is being performed in parallel to an unrelated Xen console action and the handling of a Xen console interrupt in an unprivileged guest. The closing of an event channel is e.g. triggered by removal of a paravirtual device on the other side. As this action will cause console messages to be issued on the other side quite often, the chance of triggering the deadlock is not neglectable. Note that 32-bit Arm-guests are not affected, as the 32-bit Linux kernel on Arm doesn't use queued-RW-locks, which are required to trigger the issue (on Arm32 a waiting writer doesn't block further readers to get the lock). | |||||
| CVE-2021-44879 | 1 Linux | 1 Linux Kernel | 2024-01-11 | 4.3 MEDIUM | 5.5 MEDIUM |
| In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered, leading to a move_data_page NULL pointer dereference. | |||||
| CVE-2023-4921 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. | |||||
| CVE-2023-4623 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. | |||||
| CVE-2023-4622 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.0 HIGH |
| A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. | |||||
| CVE-2023-4244 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.0 HIGH |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane transaction and nft_set element garbage collection, it is possible to underflow the reference counter causing a use-after-free vulnerability. We recommend upgrading past commit 3e91b0ebd994635df2346353322ac51ce84ce6d8. | |||||
| CVE-2023-45871 | 1 Linux | 1 Linux Kernel | 2024-01-11 | N/A | 7.5 HIGH |
| An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. | |||||
| CVE-2023-40283 | 3 Canonical, Debian, Linux | 3 Ubuntu Linux, Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled. | |||||
| CVE-2023-3611 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| 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. | |||||
| CVE-2023-3609 | 2 Debian, Linux | 2 Debian Linux, Linux Kernel | 2024-01-11 | N/A | 7.8 HIGH |
| A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_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 04c55383fa5689357bcdd2c8036725a55ed632bc. | |||||
| CVE-2023-3212 | 5 Debian, Fedoraproject, Linux and 2 more | 14 Debian Linux, Fedora, Linux Kernel and 11 more | 2024-01-11 | N/A | 4.4 MEDIUM |
| A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic. | |||||
| CVE-2023-35001 | 4 Debian, Fedoraproject, Linux and 1 more | 8 Debian Linux, Fedora, Linux Kernel and 5 more | 2024-01-11 | N/A | 7.8 HIGH |
| Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace | |||||
