Описание
In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix a user-after-free in add_pble_prm
When irdma_hmc_sd_one fails, 'chunk' is freed while its still on the PBLE
info list.
Add the chunk entry to the PBLE info list only after successful setting of
the SD in irdma_hmc_sd_one.
A vulnerability was found in the Linux kernel's RDMA/irdma driver. Improper memory management in the add_pble_prm function fails to manage memory correctly, resulting in a user-after-free condition that can lead to exploitation. This flaw allows an attacker to manipulate memory access potentially, resulting in data corruption or system crashes.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
