[REJECTED CVE] A resource management issue exists in the Linux Kernel's virtio module. When request_irq() fails in vp_find_vqs_msix(), the cleanup path incorrectly attempts to free an already released IRQ, resulting in warnings and potential system instability. This issue arises from the mishandling of virtual queue deletion during error handling.
In the Linux kernel, the following vulnerability has been resolved: virtio: delete vq in vp_find_vqs_msix() when request_irq() fails When request_irq() fails, error path calls vp_del_vqs(). There, as vq is present in the list, free_irq() is called for the same vector. That causes following splat: [ 0.414355] Trying to free already-free IRQ 27 [ 0.414403] WARNING: CPU: 1 PID: 1 at kernel/irq/manage.c:1899 free_irq+0x1a1/0x2d0 [ 0.414510] Modules linked in: [ 0.414540] CPU: 1 PID: 1 Comm: swapper/0 Not tainted 6.9.0-rc4+ #27 [ 0.414540] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-1.fc39 04/01/2014 [ 0.414540] RIP: 0010:free_irq+0x1a1/0x2d0 [ 0.414540] Code: 1e 00 48 83 c4 08 48 89 e8 5b 5d 41 5c 41 5d 41 5e 41 5f c3 cc cc cc cc 90 8b 74 24 04 48 c7 c7 98 80 6c b1 e8 00 c9 f7 ff 90 <0f> 0b 90 90 48 89 ee 4c 89 ef e8 e0 20 b8 00 49 8b 47 40 48 8b 40 [ 0.414540] RSP: 0000:ffffb71480013ae0 EFLAGS: 00010086 [ 0.414540] RAX: 0000000000000...
