CVSS: 6.4EPSS: 0%CPEs: 3EXPL: 0CVE-2023-33203 – kernel: net: qcom/emac: race condition leading to use-after-free in emac_remove()
https://notcve.org/view.php?id=CVE-2023-33203
The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based device. A race condition vulnerability was found in the Linux kernel's Qualcomm EMAC Gigabit Ethernet Controller when the user physically removes the device before cleanup in the emac_remove function. This flaw can eventually result in a use-after-free issue, possibly leading to a system crash or other undefined behaviors. • https://bugzilla.redhat.com/show_bug.cgi?id=2192667 https://bugzilla.suse.com/show_bug.cgi?id=1210685 https://cdn.kernel.org/pub/linux/kernel/v6.x/ChangeLog-6.2.9 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6b6bc5b8bd2d4ca9e1efa9ae0f98a0b0687ace75 https://access.redhat.com/security/cve/CVE-2023-33203 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2023-32258
A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_LOGOFF and SMB2_CLOSE commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.
