CVE-2021-47284

In the Linux kernel, the following vulnerability has been resolved: isdn: mISDN: netjet: Fix crash in njprobe: 'njsetup' in netjet.c might fail with -EIO and in this case 'card-irq' is initialized and is bigger than zero. A subsequent call to 'njrelease' will free the irq that has not been...

CVE-2021-47412

CVE-2021-47412 affects the Linux kernel block layer rq_qos path. The root cause was calling rq_qos_ops->done_bio for bio structures that aren’t tracked, risking a kernel panic. The fix prevents done_bio from running if the bio isn’t tracked (bio_endio paths and queue references are safer). Thi...

CVE-2021-47412 block: don't call rq_qos_ops->done_bio if the bio isn't tracked

In the Linux kernel, the following vulnerability has been resolved: block: don't call rqqosops-donebio if the bio isn't tracked rqqos framework is only applied on request based driver, so: 1 rqqosdonebio needn't to be called for bio based driver 2 rqqosdonebio needn't to be called for bio which...

CVE-2021-47373

In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Fix potential VPE leak on error In itsvpeirqdomainalloc, when itsvpeinit returns an error, there is an off-by-one in the number of VPEs to be freed. Fix it by simply passing the number of VPEs allocated, which...

CVE-2021-47284

CVE-2021-47284 (Linux kernel) relates to isdn: mISDN: netjet crash in nj_probe. The issue occurs when nj_setup may fail with -EIO, leaving card->irq initialized and >0; a subsequent nj_release frees an IRQ that wasn’t requested. The fix deletes the prior assignment to card->irq and keeps...

CVE-2021-47260 NFS: Fix a potential NULL dereference in nfs_get_client()

In the Linux kernel, the following vulnerability has been resolved: NFS: Fix a potential NULL dereference in nfsgetclient None of the callers are expecting NULL returns from nfsgetclient so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so...

CVE-2021-47235

CVE-2021-47235 affects the Linux kernel net/ethernet path: ec_bhf_remove() uses priv (netdev private data) after free_netdev() is called, enabling a use-after-free. The fixed sequence moves free_netdev() to occur after the PCI I/O unmaps (pci_iounmap) of priv, preventing access to freed memory. D...
