CVE-2022-49541

The CVE-2022-49541 issue is a Linux kernel CIFS vulnerability: a potential double free during a failed mount. It is classed as HIGH severity (LOCAL access, LOW attack complexity) with impact to confidentiality, integrity, and availability as per the CVSS metrics. Connected advisories (SUSE/RHEL-r...

CVE-2022-49522

CVE-2022-49522 concerns a Linux kernel MMC driver issue (mmc: jz4740) where DMA maps could exceed the DMA engine’s capabilities. The root cause is not a research-level flaw but an inadequate limit on the maximum segment size for DMA data transfers. The fix enforces DMA engine limits on the jz4740...

CVE-2022-49507

CVE-2022-49507 affects the Linux kernel regulator driver for the da9121 (regulator/da9121-regulator.c). The issue arises when da9121_assign_chip_model() accesses regmap without it being initialized due to an invalid chip->subvariant_id (set to -EINVAL by a malformed device tree). This leads to...

CVE-2022-49471 rtw89: cfo: check mac_id to avoid out-of-bounds

In the Linux kernel, the following vulnerability has been resolved: rtw89: cfo: check macid to avoid out-of-bounds Somehow, hardware reports incorrect macid and pollute memory. Check index before we access the array. UBSAN: array-index-out-of-bounds in rtw89/phy.c:2517:23 index 188 is out of rang...

CVE-2022-49429

CVE-2022-49429 affects the Linux kernel’s RDMA/hfi1 subsystem. When the hfi1 module is loaded with SDMA disabled (HFI1_CAP_SDMA off), a call to hfi1_write_iter() can dereference a NULL pointer, causing a kernel panic through the I/O path (sdma_select_user_engine → hfi1_user_sdma_process_request →...

CVE-2022-49418 NFSv4: Fix free of uninitialized nfs4_label on referral lookup.

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Fix free of uninitialized nfs4label on referral lookup. Send along the already-allocated fattr along with nfs4fslocations, and drop the memcpy of fattr. We end up growing two more allocations, but this fixes up a crash as:...

CVE-2022-49418

The CVE affects the Linux kernel in NFSv4 handling, where an uninitialized nfs4_label could be freed during referral lookup, leading to a crash. The fix reuses the already-allocated fattr with nfs4_fs_locations and drops the memcpy of fattr, avoiding two extra allocations and preventing the crash...

CVE-2022-49390 macsec: fix UAF bug for real_dev

In the Linux kernel, the following vulnerability has been resolved: macsec: fix UAF bug for realdev Create a new macsec device but not get reference to realdev. That can not ensure that realdev is freed after macsec. That will trigger the UAF bug for realdev as following:...
