In the Linux kernel, the following vulnerability has been resolved:

params: fix charp corruption on allocation failure

param_set_charp() stores charp parameters in allocated memory after slab is available, and releases the previous value when the parameter is updated.

The previous value is released before the replacement allocation succeeds. If kmalloc_parameter() fails, the setter returns -ENOMEM with the parameter left as NULL.

Failing zswap's compressor update before zswap is initialized can later trigger:

BUG: kernel NULL pointer dereference, address: 0000000000000000 RIP: 0010:strcmp+0x10/0x30 Call Trace: zswap_setup+0x3b1/0x490 zswap_enabled_param_set+0x5b/0xa0 param_attr_store+0x93/0xe0 module_attr_store+0x1c/0x30 kernfs_fop_write_iter+0x116/0x1f0

Allocate and copy the replacement first, then replace the parameter value only after allocation succeeds.

Upstream kernel 6.18.55 version fixes bugs and vulnerabilities. The kmod-xtables-addons, kmod-virtualbox, kmod-nvidia-current-wopengpu & drakx-installer-images packages have been updated to work with this new kernel.

Vanilla upstream kernel version 6.18.55 fixes vulnerabilities. For information about the vulnerabilities see the links.

These are all security issues fixed in the kernel-devel-7.2.7-1.1 package on the GA media of openSUSE Tumbleweed.
