Description
In the Linux kernel, the following vulnerability has been resolved:
s390/zcrypt: Fix memory leak with CCA cards used as accelerator
Tests showed that there is a memory leak if CCA cards are used as
accelerator for clear key RSA requests (ME and CRT). With the last
rework for the memory allocation the AP messages are allocated by
ap_init_apmsg() but for some reason on two places (ME and CRT) the
older allocation was still in place. So the first allocation simple
was never freed.
Affected configurations
• linux linux kernel (>= 6.16 < 6.18.22)
• linux linux kernel (>= 6.19 < 6.19.12)
• linux linux kernel 7.0
