2024-06-06: CVE-2023-52477 was added to this advisory.
A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can lead to a use-after-free vulnerability and crash. (CVE-2023-3397)
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-2023-46813)
In the Linux kernel, the following vulnerability has been resolved:
usb: hub: Guard against accesses to uninitialized BOS descriptors (CVE-2023-52477)
In the Linux kernel, the following vulnerability has been resolved:
HID: logitech-hidpp: Fix kernel crash on receiver USB disconnect (CVE-2023-52478)
In the Linux kernel, the following vulnerability has been resolved:
x86/alternatives: Disable KASAN in apply_alternatives() (CVE-2023-52504)
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srp: Do not call scsi_done() from srp_abort() (CVE-2023-52515)
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-2023-5717)
