CVE-2023-3439 – Ubuntu Security Notice USN-6246-1
https://notcve.org/view.php?id=CVE-2023-3439
28 Jun 2023 — A flaw was found in the MCTP protocol in the Linux kernel. The function mctp_unregister() reclaims the device's relevant resource when a netcard detaches. However, a running routine may be unaware of this and cause the use-after-free of the mdev->addrs object, potentially leading to a denial of service. It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to c... • http://www.openwall.com/lists/oss-security/2023/07/02/1 • CWE-416: Use After Free •
CVE-2023-3212 – kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()
https://notcve.org/view.php?id=CVE-2023-3212
23 Jun 2023 — 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. A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel.

CVE-2023-3220 – Ubuntu Security Notice USN-6385-1
https://notcve.org/view.php?id=CVE-2023-3220
20 Jun 2023 — An issue was discovered in the Linux kernel through 6.1-rc8. dpu_crtc_atomic_check in drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c lacks check of the return value of kzalloc() and will cause the NULL Pointer Dereference. It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. William Zhao discovered that the Traffic Control subsystem in the L... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93340e10b9c5fc86730d149636e0aa8b47bb5a34 • CWE-476: NULL Pointer Dereference •
CVE-2023-3022 – kernel: IPv6: panic in fib6_rule_suppress when fib6_rule_lookup fails
https://notcve.org/view.php?id=CVE-2023-3022
19 Jun 2023 — A flaw was found in the IPv6 module of the Linux kernel. The arg.result was not used consistently in fib6_rule_lookup, sometimes holding rt6_info and other times fib6_info. This was not accounted for in other parts of the code where rt6_info was expected unconditionally, potentially leading to a kernel panic in fib6_rule_suppress. • https://bugzilla.redhat.com/show_bug.cgi?id=2211440 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVE-2023-35823 – kernel: saa7134: race condition leading to use-after-free in saa7134_finidev()
https://notcve.org/view.php?id=CVE-2023-35823
18 Jun 2023 — An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in drivers/media/pci/saa7134/saa7134-core.c. A race condition was found in the Linux kernel's saa7134 device driver. This occurs when removing the module before cleanup in the saa7134_finidev function which can result in a use-after-free issue, possibly leading to a system crash or other undefined behaviors.
