| 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 ...

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

And use devm_platform_get_and_ioremap_resource() to simplify code.

|
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.
