CVE-2024-50067 – uprobe: avoid out-of-bounds memory access of fetching args
https://notcve.org/view.php?id=CVE-2024-50067
28 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: uprobe: avoid out-of-bounds memory access of fetching args Uprobe needs to fetch args into a percpu buffer, and then copy to ring buffer to avoid non-atomic context problem. Sometimes user-space strings, arrays can be very large, but the size of percpu buffer is only page size. And store_trace_args() won't check whether these data exceeds a single page or not, caused out-of-bounds memory access. It could be reproduced by following steps: 1.... • https://git.kernel.org/stable/c/dcad1a204f72624796ae83359403898d10393b9c • CWE-416: Use After Free •
CVE-2024-50066 – mm/mremap: fix move_normal_pmd/retract_page_tables race

23 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: mm/mremap: fix move_normal_pmd/retract_page_tables race In mremap(), move_page_tables() looks at the type of the PMD entry and the specified address range to figure out by which method the next chunk of page table entries should be moved. At that point, the mmap_lock is held in write mode, but no rmap locks are held yet. For PMD entries that point to page tables and are fully covered by the source address range, move_pgt_entry(NORMAL_PMD, .... • https://git.kernel.org/stable/c/1d65b771bc08cd054cf6d3766a72e113dc46d62f • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

CVE-2022-48952 – PCI: mt7621: Add sentinel to quirks table

21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: PCI: mt7621: Add sentinel to quirks table Current driver is missing a sentinel in the struct soc_device_attribute array, which causes an oops when assessed by the soc_device_match(mt7621_pcie_quirks_match) call. This was only exposed once the CONFIG_SOC_MT7621 mt7621 soc_dev_attr was fixed to register the SOC as a device, in: commit 7c18b64bba3b ("mips: ralink: mt7621: do not use kzalloc too early") Fix it by adding the required sentinel.

CVE-2022-48949 – igb: Initialize mailbox message for VF reset
https://notcve.org/view.php?id=CVE-2022-48949
21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: igb: Initialize mailbox message for VF reset When a MAC address is not assigned to the VF, that portion of the message sent to the VF is not set. The memory, however, is allocated from the stack meaning that information may be leaked to the VM. Initialize the message buffer to 0 so that no information is passed to the VM in this case.
