CVE-2022-49450 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix listen() setting the bar too high for the prealloc rings AF_RXRPC's listen() handler lets you set the backlog up to 32 (if you bump up the sysctl), but whilst the preallocation circular buffers have 32 slots in them, one of them has to be a dead slot because we're using CIRC_CNT(). This means that listen(rxrpc_sock, 32) will cause an oops when the socket is closed because rxrpc_service_prealloc_one() allocated one ...

CVE-2022-49449 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code.
CVE-2022-49448 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: soc: bcm: Check for NULL return of devm_kzalloc() As the potential failure of allocation, devm_kzalloc() may return NULL. Then the 'pd->pmb' and the follow lines of code may bring null pointer dereference. Therefore, it is better to check the return value of devm_kzalloc() to avoid this confusion.
CVE-2022-49445 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: core: Fix possible null-ptr-deref in sh_pfc_map_resources() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.

CVE-2022-49400 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: md: Don't set mddev private to NULL in raid0 pers->free In normal stop process, it does like this: do_md_stop | __md_stop (pers->free(); mddev->private=NULL) | md_free (free mddev) __md_stop sets mddev->private to NULL after pers->free. The raid device will be stopped and mddev memory is free. But in reshape, it doesn't free the mddev and mddev will still be used in new raid. In reshape, it first sets mdd ...

In the Linux kernel, the following vulnerability has been resolved: serial: 8250_aspeed_vuart: Fix potential NULL dereference in aspeed_vuart_probe platform_get_resource() may fail and return NULL, so we should better check it's return value to avoid a NULL pointer dereference.
CVE-2022-49376 1 Linux 1 Linux Kernel 2025-10-01 N/A 5.5 MEDIUM
In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix potential NULL pointer dereference If sd_probe() sees an early error before sdkp->device is initialized, sd_zbc_release_disk() is called. This causes a NULL pointer dereference when sd_is_zoned() is called inside that function. Avoid this by removing the call to sd_zbc_release_disk() in sd_probe() error path. This change is safe and does not result in zone information memory leakage because the zone information ...
