CVE-2022-50027

CVE-2022-50027 is a Linux kernel issue affecting the SCSI lpfc path, where a missing free for the iocbq on failure to issue the CMF WQE can cause a memory leak. The root cause is that if lpfc_sli4_issue_wqe fails (ret_val non-zero), the iocbq request structure is not consistently freed, leading t...

CVE-2022-50026

CVE-2022-50026 concerns a Linux kernel vulnerability where the NIC queue offset calculation could shift out of bounds during NIC queue validation. The root cause is related to how habanalabs/gaudi handling interacts with NIC queues, leading to potential out-of-bounds access. The CVSS metrics indi...

CVE-2022-50025

CVE-2022-50025 affects the Linux kernel. It fixes a memory leak in an error path: bitmap_zalloc() allocated in afu_allocate_irqs() must be balanced with a corresponding bitmap_free() in the error handling path. The issue was resolved by correcting the memory management in the afu_allocate_irqs() ...

CVE-2022-50024

CVE-2022-50024 affects the Linux kernel DMA engine (dmaengine) dw-axi-dmac. The issue occurs when axi_chan_dump_lli() is given a NULL LLI pointer, which can trigger an OOPS by attempting to read fields from a NULL structure. The fix is to print a NULL LLI and exit instead of dereferencing it. Aff...

CVE-2022-50023 dmaengine: dw-axi-dmac: ignore interrupt if no descriptor

In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: ignore interrupt if no descriptor If the channel has no descriptor and the interrupt is raised then the kernel will OOPS. Check the result of vchannextdesc in the handler axichanblockxfercomplete to avoid...

CVE-2022-50021 ext4: block range must be validated before use in ext4_mb_clear_bb()

In the Linux kernel, the following vulnerability has been resolved: ext4: block range must be validated before use in ext4mbclearbb Block range to free is validated in ext4freeblocks using ext4inodeblockvalid and then it's passed to ext4mbclearbb. However in some situations on bigalloc file syste...

CVE-2022-50020

CVE-2022-50020 affects the Linux kernel ext4 filesystem: the patch prevents online resizing to an unaligned/partial cluster boundary. The issue could cause the last resize iteration to grow the filesystem by a negative amount, tripping a BUG_ON and leaving the in-memory superblock corrupted. Conn...

CVE-2022-50019 tty: serial: Fix refcount leak bug in ucc_uart.c

In the Linux kernel, the following vulnerability has been resolved: tty: serial: Fix refcount leak bug in uccuart.c In socinfo, offindnodebytype will return a node pointer with refcount incremented. We should use ofnodeput when it is not used anymore...

CVE-2022-50017 mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start

In the Linux kernel, the following vulnerability has been resolved: mips: cavium-octeon: Fix missing ofnodeput in octeon2usbclocksstart We should call ofnodeput for the reference 'uctlnode' returned by ofgetparent which will increase the refcount. Otherwise, there will be a refcount leak bug...
