https://notcve.org/view.php?id=CVE-2022-49731
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of ata_host_alloc_pinfo() points to an array starting with a NULL pointer, there's going to be a kernel oops as the 'pi' local variable won't get reassigned from the initial value of NULL. Initialize 'pi' instead to '&ata_dummy_port_info' to fix the possible kernel oops for good...

CVE-2022-49730 – scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is aborted
https://notcve.org/view.php?id=CVE-2022-49730
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Resolve NULL ptr dereference after an ELS LOGO is aborted A use-after-free crash can occur after an ELS LOGO is aborted. Specifically, a nodelist structure is freed and then ndlp->vport->cfg_log_verbose is dereferenced in lpfc_nlp_get() when the discovery state machine is mistakenly called a second time with NLP_EVT_DEVICE_RM argument. Rework lpfc_cmpl_els_logo() to prevent the duplicate calls to release a nodelist structure. In... • https://git.kernel.org/stable/c/5e83869e29448958f8ae2c6911f350318f75e4fc •

CVE-2022-49729 – nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred Similar to the handling of play_deferred in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought a patch might be needed here as well. Currently usb_submit_urb is called directly to submit deferred tx urbs after unanchor them. So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb and cause memory leak. Put those urbs in tx_anchor to av... • https://git.kernel.org/stable/c/1eb0afecfb9cd0f38424b82bd9aaa542310934ee •

CVE-2022-49710 – dm mirror log: round up region bitmap size to BITS_PER_LONG
https://notcve.org/view.php?id=CVE-2022-49710
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: dm mirror log: round up region bitmap size to BITS_PER_LONG The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan. • https://git.kernel.org/stable/c/29121bd0b00ebb9524971a583fea4a2f7afe8041 •

It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserv... • https://git.kernel.org/stable/c/0dc2fca8e4f9ac4a40e8424a10163369cca0cc06 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: dm raid: fix accesses beyond end of raid member array On dm-raid table load (using raid_ctr), dm-raid allocates an array rs->devs[rs->raid_disks] for the raid device members. rs->raid_disks is defined by the number of raid metadata and image tupples passed into the target's constructor.
