[PATCH openEuler-1.0-LTS 1/4] net/nfc: fix use-after-free llcp_sock_bind/connect
by Yang Yingliang 26 May '21

26 May '21

From: Or Cohen <orcohen(a)paloaltonetworks.com> stable inclusion from linux-4.19.191 commit 48fba458fe54cc2a980a05c13e6c19b8b2cfb610 CVE: CVE-2021-23134 -------------------------------- commit c61760e6940dd4039a7f5e84a6afc9cdbf4d82b6 upstream. Commits 8a4cd82d ("nfc: fix refcount leak in llcp_sock_connect()") and c33b1cc62 ("nfc: fix refcount leak in llcp_sock_bind()") fixed a refcount leak bug in bind/connect but introduced a use-after-free if the same local is assigned to 2 different sockets. This can be triggered by the following simple program: int sock1 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); int sock2 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); memset( &addr, 0, sizeof(struct sockaddr_nfc_llcp) ); addr.sa_family = AF_NFC; addr.nfc_protocol = NFC_PROTO_NFC_DEP; bind( sock1, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) bind( sock2, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) close(sock1); close(sock2); Fix this by assigning NULL to llcp_sock->local after calling nfc_llcp_local_put. This addresses CVE-2021-23134.

[PATCH kernel-4.19 1/2] x86/apic/vector: Force interupt handler invocation to irq context
by Yang Yingliang 26 May '21

26 May '21

From: Thomas Gleixner <tglx(a)linutronix.de> mainline inclusion from mainline-5.7 commit 008f1d60fe25810d4554916744b0975d76601b64 category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- Sathyanarayanan reported that the PCI-E AER error injection mechanism can result in a NULL pointer dereference in apic_ack_edge(): BUG: unable to handle kernel NULL pointer dereference at 0000000000000078 RIP: 0010:apic_ack_edge+0x1e/0x40 Call Trace: handle_edge_irq+0x7d/0x1e0 generic_handle_irq+0x27/0x30 aer_inject_write+0x53a/0x720 It crashes in irq_complete_move() which dereferences get_irq_regs() which is obviously NULL when this is called from non interrupt context. Of course the pointer could be checked, but that just papers over the real issue. Invoking the low level interrupt handling mechanism from random code can wreckage the fragile interrupt affinity mechanism of x86 as interrupts can only be moved in interrupt context or with special care when a CPU goes offline and the move has to be enforced. In the best case this triggers the warning in the MSI affinity setter, but if the call happens on the correct CPU it just corrupts state and might prevent further interrupt delivery for the affected device. Mark the APIC interrupts as unsuitable for being invoked in random contexts. This prevents the AER injection from proliferating the wreckage, but that's less broken than the current state of affairs and more correct than just papering over the problem by sprinkling random checks all over the place and silently corrupting state.

[PATCH kernel-4.19 01/15] x86/cpufeatures: Enumerate the new AVX512 BFLOAT16 instructions
by Yang Yingliang 26 May '21

26 May '21

From: Fenghua Yu <fenghua.yu(a)intel.com> mainline inclusion from mainline-v5.3-rc1 commit b302e4b176d00e1cbc80148c5d0aee36751f7480 category: feature bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=44 CVE: NA ----------------------------------------------- AVX512 BFLOAT16 instructions support 16-bit BFLOAT16 floating-point format (BF16) for deep learning optimization. BF16 is a short version of 32-bit single-precision floating-point format (FP32) and has several advantages over 16-bit half-precision floating-point format (FP16). BF16 keeps FP32 accumulation after multiplication without loss of precision, offers more than enough range for deep learning training tasks, and doesn't need to handle hardware exception. AVX512 BFLOAT16 instructions are enumerated in CPUID.7.1:EAX[bit 5] AVX512_BF16. CPUID.7.1:EAX contains only feature bits. Reuse the currently empty word 12 as a pure features word to hold the feature bits including AVX512_BF16. Detailed information of the CPUID bit and AVX512 BFLOAT16 instructions can be found in the latest Intel Architecture Instruction Set Extensions and Future Features Programming Reference.

[PATCH kernel-4.19 1/7] genirq: Add protection against unsafe usage of generic_handle_irq()
by Yang Yingliang 26 May '21

26 May '21

From: Thomas Gleixner <tglx(a)linutronix.de> mainline inclusion from mainline-5.7 commit c16816acd08697b02a53f56f8936497a9f6f6e7a category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- In general calling generic_handle_irq() with interrupts disabled from non interrupt context is harmless. For some interrupt controllers like the x86 trainwrecks this is outright dangerous as it might corrupt state if an interrupt affinity change is pending. Add infrastructure which allows to mark interrupts as unsafe and catch such usage in generic_handle_irq().
